Patented July 15,V 1930 UNITED STATES OFFICE LEON GRAUMAN, oF DENVER, oozto'n'ano Application led March 17, 1928. Serial No;y 262,466.,`

This invention relates to improvements in soda fountains and more particularly to the element thereof by which milk or chocolate and other syrups are stored in convenient vicinity to a pump device capable of drawing the liquids into vessels, for use in the preparation of diverse beverages.

In soda fountain structures at present in use the arrangement of the container for the l0 milk and other liquids, and the pump, is such that whenever the container is supplied with fresh liquid, the pump must be removed with the lid normally covering the container or some other laborious and time-taking operation or adjustment is required by reason of the presence of the pump device.

It is an object of the present invention to provide a jar unit for soda fountains, of the above-described character which may be lled with liquid without disturbing or interfering with the pump by which the liquid is drawn from the unit.

A further object of the invention is to provide in a unit of this kind, meansr f-or agitating the liquid contents thereof by the operation of the pump, which is especially desirable for mixing cream and milk, and still other objects reside in details of construction and a novel arrangement of parts as will fully appear in the course of the following description.

An embodiment of my invention has been shown in the Yaccompanying drawings, in which like characters of reference designates corresponding parts throughout the views,

and in which- Figure 1 represents a partially broken face view of a jar unit constructedin accordance with my invention, in its operative position with relation to the splash-back and workboard of a soda fountain structure;

Figure 2, a section taken in a slanting plane indicated by the line 2-2 in Figure l; and

Figure 3, an enlarged section taken on the V line 3- 3 of Figure 1. y

Referring further tothe drawings, 5 designates the counter of a soda fountain structure, 6 the splash-back, and 7 the work-board of the same.

The jar unit, designatedl in its entirely by the numeral 8, comprises a container slantingforwardly from the. splash-back. The containerfis oblong in cross section and its open top is normally covered by two flanged lids 9 and 10 placed side by iside.. One-ofthe lids has a'handle 12 forits manipulation and the other lid is equipped with 'a flanged top 13 for the support of the spout 14 ofra pump element and for the guidance of the reciprocating plunger rod 15 of uo thesame. I Y A, f

The cylinder 16 of the :pump yelement'is suspended fromfthe lid ofthe container by rodsrlf? and'it .is in its operative position supported on the bottom ofthe container immedia-telybeneath fthe lid. The container proper preferably consists of a porcelain jar. 18/en'cl'os'ed ina housing 19 formed integral with the fountain structure.

The lids covering the container as stated hereinbefore, are supported 'upon the housing and the space'in the housing around the j ar may be filled with ice for the purpose of cooling and preserving the contents of the container. l

The stem portion of the pump element within the container carries an agitator 20, preferably in the form of opposed screwblades, which when the stem is moved in the operation ofthe pump, stirs the liquid contents of the jar. Thek agitator is preferably made in the form of a helical propeller, and by rotating the plunger rod, the milk may be stirred without operating the pump. The agitator is particularly advantageous in the use of milk inasmuch as. it mixes the cream with the milk before it is drawn through theV spout ofthe pump and into a vessel held beneath the same, when the stem is revolved or turned.

Having thus described the mechanical construction of my invention, its advantages will be readily apparent. After the container has been filled it is closed by the two lids and any part of its contents may be discharged into a vessel held beneath the spout of the pump, by manual reciprocation of the stem 15 of the same.

During the operation of the pump, the contents of the container are stirred by the agi- Iii tator so that liquids having separable components such as cream and milk, are thoroughly mixed before they are discharged from the container.

5 To refill the jar after it has been emptied, it is but necessary to remove the lid 9. The lid and the pump remain in place and are removed only for cleaning purposes or reair.

m It will thus be seen that ,my improved jar unit has many advantages over those at present in use, which require the removal of the entire pump-mechanism each time the unit is supp ied with fresh material. u Y

l5 The construction of the improved unit is simple and practical and its osition with relation to the work-board of t e fountain permits of its being placed in convenient vicinitytn the refrigerated vats in which the milk bottles are stored.l v f What- I claim and desireto secure by Let- Iers Patentis:

'1. Ian a soda fountain structure, a jar, a lmp in the jar having a rotary stem projectmg outside the same, and an agitator on the stem within the jar.

2. In ay soda. fountain structure, a jar, a pump in the jar having a rotary reciprocating stem projecting outside the same, and an agi tator on thestem within the jar.

In testimony whereof I have aixed my signature.

LEON GRAUMAN.
